Hello anyone that can help would be great when it finishs a dvd creating and starts to burn it freezes up and can not get nothing to work I have done disk defragment and disk cleanup really dont know what else to do it was working fine til last night any help would be appricated thank you for your time

It may be hanging on the .wav file at the end of the burn.
Click on the preferences tab in Clonedvd, blank the "successful completion of operations" box, and see if this resolves your problem.
You can use the browse button next to it to reinstate success .wav

3. Try a custom size of 4300 if you're using regular single layer blank media

Try setting a custom size of 4300 near the quality bar in Clonedvd (but if you're using good media, such as Taiyo Yuden Premium, Verbatim, Maxell Plus, or Maxell Broadcast Quality, you shouldn't have to) if you're using regular single layer dvd-5 (4.7GB) discs. Bad burn quality is notorious around the end of discs. Using a custom disc size of 4300 ensures you won't be burning to the end.

C. Try lowering your burn speed (not below 4x; if you have a 16x burner and 16x rated media try writing to it at 12x instead of 16x; an 8x burn speed on 16x rated media wouldn't be a bad idea either)

D. Avoid sticker labels (they tend to cause problems)

E. Try setting a custom size of 4300 in Clonedvd (but if you're using good media, you shouldn't have to) if you're using regular single layer dvd-5 (4.7GB) discs.

Bad burn quality is notorious around the end of discs (see step E)
and also at layer breaks when using low quality DL media (use Verbatim +R DL media made in Singapore, and change the booktype to "dvd-rom")
